Describe the structural organization shared by the cilia and flagella?

1 answer:

8 0

Both flagella and cilia have a common structural arrangement of microtubules referred to as "9 + 2 array." A single cilium or flagellum is made up of string of nine microtubule doublets that surround a single microtubule doublet in the center.

Flagella are hair-like structures which are usually long and they extend from the plasma membrane. They are used to propel or move an entire cell, for example sperm cell.

Cilia are short hair-like structures that are used to move entire cells. An example is paramecia. Cilia can also be found lining the outer surface of cells such as those of the respiratory tract where they move trapped particles up toward the nose and mouth.

mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

Which of the following would most likely be found in the sands at Myrtle Beach?

sergejj [24]

The correct answer is option A, that is, placer deposits.

The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.

The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.

Answer:

E. glucosuria (glucose in the urine)

Explanation:

Generally, glycosuria occurs in patients with kidney changes due to diseases such as Wilson's disease or cystinosis, can also be a hereditary problem, but is not expected in patients with kidney damage caused by prolonged lithium use.

Normally, the kidneys filter the blood, eliminating all substances that are not necessary for the body to function, while glucose is reabsorbed in the blood because of its importance in energy production, but people with renal glycosuria do not reabsorb glucose. , which causes it to be eliminated in the urine, occurring glucosuria.
